SPECIFICATION forming partof Letters Patent No. 290,515, dated December 18, 1833.

Application filed August 23,1383. (Model) To all whom it may concern:

Be it known that I, ARTHUR LEE BATTSON, of Morrisburg, in the county of Dundas, Province of Ontario and Dominion of Canada, have invented ccrtai'nnew and useful Improvements in Presses for Sacking Bran, Sawdust, and other Substances, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1, Sheet 1, is a rear elevation of my improvement, parts being broken away. Fig. 2, Sheet 2, is a sectional side elevation of the same, and showing the position of the feedspout, the sack-case being shown open. Fig. 3, Sheet 2, is a side elevation of the upper end of the follower-screw, and showing the balancing-weight, cord, and guide-pulleys. Fig. 4, Sheet 2, is an under side view of the large gear-wheel and the half-nuts and their springs, the screw being shown in section. Fig. 5, Sheet 2, is a perspective view of the sack-hoop and its bottom plate. Fig. 6, Sheet 2, is a plan view of the top plate that carries the sackcover and the fasteningpins.

The object of this invention is to provide a mechanism for compressing bran, sawdust, and other substances into sacks.

The invention consists in a sacking-press constructed with a receiving-case having a hinged rear plate provided with a top flange, and operated by a set of pivoted bars and a shaft having rigid arms and lever for receiving and shutting off the material. The sackcase is formed of hinged doors having pins at their upper ends to engage with perforations in the lower end of the receiving-case, to inclose the sack and keep it in position while being filled. Below the sack-case is placed a bottom plate attached to a screw, and raised and lowered by a nut and gear-wheels operating upon the said screw. Upon the bottom plate, and within the sack-case, is placed a plate provided with a U-shaped bar having holes in its ends, and designed, in connection with pins and a plate carried by the follower, provided with finger-springs, catch-springs,

and a socket, and carrying a sack-cover, to be used for holding the compressed material in place until the cover has been sewed to the sack. The follower-screw passes through a gearwheel, which has sliding conical half-nuts connected with its lower side, and forced into gear with the said screw by a conical collar, operated by a lever and rod to throw the fol lowerscrew into and out of gear with the driving mechanism. screw-driving gear-wheel is lessened by conical rollers interposed between the conical upper side of the said gear-wheel and a conicali'accd plate attached to the top of the pressframe, the said rollers being pivoted to and kept in proper relative position by concentric rings. The shaft of the driving gear-wheel revolves in bearings sliding in ways, and connected by a cord with a shaft provided witha cam held by a springprcssed lever, tripped at the proper time by a collar attached to the follower-screw, the cam-shaft being provided with a lever and hanging cord, so that the driving mechanism can be readily thrown into cally at the proper time. The screw and follower are raised when released from the halfnuts by a weightv connected with the said screw by a cord passing over guide-pulleys, all constructed and operating as will be hereinafter fully described. 7

A represents the base of the press, to which are attached the lower ends of four posts, B. The upper ends of the posts B are attached to the top 0 of the press. The frame can be strengthened, if desired, by tie-rods attached to the base and top A G and extending along the sides of the posts 13. The tie-rods are not shown in the drawings.

To the top plate or frame, 0, are attached brackets or hinges G, to the lower ends of which is attached the upper end of the presscase D. The rear edges of the sides of the case D incline outward, as shown in Fig. 2, and are connected at their lower ends by the narrow stationary part D of the rear side of the said case. The movable part F of the The thrust-friction of the gear and will be thrown out of gear automatirear side of the case D is hinged at its lower position, as indicated in dotted lines in Fig. 2,

for convenience in introducing the material to be sacked, and inward into a vertical position, as shown in full lines in Fig. 2, when the material is to be compressed into a sack.

Upon the upper end of the part Fis formed an outwardly-proj ecting flange, G, which ,when the said part F is swung inward, serves as a slide or gate to close the discharge-opening of the feed-spout H and shut off the feed. The flange G is supported against the mouth of the hopper H by a cross-bar, I, attached to the upper parts of the rear edges of the sides of the receiving-case D.

To the upper part of the rear side, F, are hinged, by a rod J, rocking in bearings attached to the said side, the inner ends of two bars, K, the outer ends of which are hinged to the inner ends of two bars, L, by a rod, M. The outer ends of the bars L are hinged by a rod, N, to the outer ends of the arms 0, the inner ends of which are rigidly attached to. the side plates of the receiving-case D. WVith the adjacent ends of the bars K L are connected, by the rod M, the upper ends of the bars P, the lower ends of which are connected by a rod, Q, with the outer ends of the arms R. The inner ends of the arms R are rigidly attached to a rod, S, which rocks in bearings attached to the sides of the case D, and to one of its ends is attached a lever, T. WVith this construction, by operating the lever T, the plate F can be readily swung outward to adjust the case D to receive the material to be sacked, and swung inward, pressing the received material into the middle part of the case D, so that it will all be forced downward by the press-follower, hereinafter described, the bars K L acting as toggles, so that the plate F will be forced inward with great power.

The sack-case is formed of four doors, U, which are hinged to each other in pairs, and the pairs of doorsat one edge are hinged to a rod, V, the upper end of which is attached to the receiving-case D. The lower end of the rod V isattached to the base A, the floor, or other suitable support. The other edges of the pairs of doors U are provided with eyes to receive a rod, to fasten the doors U in place when closed. 7

The mouth of the sack, X, to be filled is drawn over the lower end of the receivingcase D, and is secured in place and held against the downward pressure of the material being sacked by pins Y, attached to the upper parts of the doors U, and which, when the said doors are closed, pass through the said sack near its edge and into holes Z in the shell of the case D. The bottom of the sack rests upon a plate, a, secured at its middle part to the middle part of a bar, I), the end parts of which, at the opposite edges of the plate a, are bent upward and have holes formed in their ends to receive the pins 0, for the purpose hereinafter set forth. Reecsses d are formed in the upper ends of two opposite doors, U, to allow the pins 0 to be inserted while the said doors are closed.

6 is the sack-cover, the edges of which are turned up over the edges of the top plate, f, and are secured in place by being passed beneath the finger-springs 9, attached to the upper side of the said plate f.

To the upper side of the top plate, f, is secured a tubular socket, 71, the ends of which are designed to receive the pins 0. To the upper side of the plate f are also secured springcatches t, to enter holes in the lower side of the follower j, so that the said plate f and sack-cover 6 can be carried up into the case D by the said follower, and held while the ma terial is being fed into the said case and pressed into the sack. XVith this construction, when the material has been compressed into the sack X, the pins 0 are inserted through the re cesses d, the holes in the bar or hoop b, the upper part of the sack X and into the socket h, to hold the compressed material from expanding when withdrawn from the pressure. The sack thus filled and packed is converted or compressed into a solid square or boxshaped mass, whereby the same is capable of storage with greater facility, after the manner of storing boxed goods. The bottom plate, It, upon which the plate a and the sack Xrest While the said sack is being filled, is lowered, the sack and its hoop are removed, another sackhoop and top plate are inserted in the sack case U, the bottom plate, 7.1, is raised, the said sack-case U is closed, and material is again admitted into the receiving-case D. \Vhile the sack is being filled the attendant sews the edge of the sack X to the edge of the cover 0 and detaches the plate and hoop a b and the top plate, f, ready to be again used.

To the center of the lower side of the plate k, which forms the bottom of the sack-case, is attached the upper end of the screw Z, which passes down through the base A. Upon the screw Z is placed a beveled gear wheel, 1%, which has an interior screw-thread fitting into the thread of the said screw 7, and which is swiveled to the base A.

Into the teeth of the beveledgear wheel at mesh the teeth of the beveled-gear wheel a. attached to the inner end of the horizontal shaft 0, which revolves in bearings attached to the base A.

To the outer end of the shaft 0 is attached the beveled-gear wheel 19, into the teeth of which mesh the teeth of the beveled gear wheel q, attached to the upright shaft 0'. The shaft r revolves in bearings attached to the posts B, or other suitable support, and has a hand-wheel, 8, attached to its upper end, for convenience in operating it to raise and lower the bottom plate, 76, as may be required.

To the center of the upper side of the followerj is rigidly attached the lower end of the screw it, which passes up through the receiving-case D and through the hub of the large beveled-gear wheel a. The hub of the gear- ICO IIO

wheel "a is extended upward, passes through a bearing in the top G of the press-frame, and has a flange, 11, around its upper end, to rest upon the upper side of the said top and support the weight of the said wheel.

In a dovetailed groove in the lower side of the gear-wheel a, or in plates in, securedto the said lower side, are placed the base-plates a of the half-nuts y, so that the said half-nuts can be moved to throw them into and out of gear with the screw '1. The outward movement of the half-nuts 1?] is limited by pins z or other stops attached to the wheel a, and the said half-nuts are held outward by springs 1, at-

tached atone end to the wheel a or plates 10, and resting at their outer ends against pins 2, or other projections attached to or formed upon the base-plates x of thehalfnuts y. The outer surface of the half-nuts 3 is tapered or made conical to fit into the conical interior of the collar 3, in the outer surface of which is formed an annular groove, 4, to receive the forked end of the lever 5. The lever 5 is pivoted to a hanger, 6, attached to the top of the press-frame, and to the outer end of the said leveris attached the upper end of a rod, 7 the lower end of which hangs in such aposition that it can be readily reached and operated by the attendant to raise and lower the collar 3, and thus throw the half-11utsy into and out of gear with the screw it.

To the upper end of the screw 15 is attached the end of a cord, 8, which passes over guidepulleys 9, pivoted to the frame of the building, or other suitable support.

To the outer end of the cord 8 is attached a weight, 10, of sufficient gravity to overbalance the weight of the screw 75 and follower j. Vith this construction, when the screw 15 and follower are to be raised, the attendant raises the rod 7 to lower the collar 3 and release the half-nuts '11, which are immediately moved back by the spring 1, allowing the said screw t and follower j to be'raised by the weight 10.

The upward thrust of the gear-wheel 4/, is relieved by the conical rollers 11, interposed between the conical middle part of the upper side of the said gear-wheel a, and the conical lower side of the plate 12, attached to the lower side of the top 0 of the press-frame. The rollers 11 are pivoted to concentric rings 13 1e, placed upon the upper side of the gear-wheel a, and through which the hub of the said gearwhcel passes. The taper of the rollers 11 should be such as to cause them to revolve without sliding.

Into the teeth of the gear-wheel a mesh the teeth of the small gear-wheel 15, attached to the inner end of thehorizontal shaft 16, which revolves in a bearing, 17, sliding upon the posts B, or other ways, and in abearing in the upper end of the post 18, or other suitable support. Motion is given to the shaft 16, by a pulley and belt, geanwheels, or other suitable means, from a steam-engine or other convenient power.

To the sliding bearing 17 is attached the end of a rope or chain, 19, the other end of which passes around and is attached to the shaft 20, or to a drum secured to the said shaft.

To the shaft 20 is also secured, or u'ponitis formed, a cam, 21, against which rests the end of a lever, pivoted to a support, 23, attached to the top 0 of the press-frame in such a position that the other end of the said lever will be at the side of and close to the screw t. The outer end of the lever 22 is held against the cam 21 by a spring, 24, attached to the top 0 of the pressframe, and which presses against the lower side of the inner end of the said lever 22.

To the upper part of the screw it is secured, by a set-screw, 25, or other suitable means, a collar, 26, in such a position that when the screw 15 and follower j have been lowered to the desired point the said collar will strike and depress the inner end of the lever 22, raising its outer end away from the shoulder of the cam 21, and allowing the gear-wheel 15 to be thrown out of gear by its own weight and by the weight of the bearing 17.

To the end of the shaft 20 is rigidly attached the inner end of an arm or lever, 27, to the outer end of which is attached the upper end of a cord, 28, the lower end of which hangs in such a position that it can be readily grasped and operated by the attendant to turn the shaft 20 and cam 21, winding up the cord 19, raising the gear-wheel 15 into gear with the gearwheel a, and allowing the end of the trip lever 22 to drop against the shoulder of the cam 21, and thus lock the gear-wheels a 15 in gear.

In using this machine, when the sack and its hoop have been arranged in the sack-case and the platef and sack-cover attached to the followerj, the lever is operated to release the half-nuts y and allow the screw it and follower j to rise out of the way. The plate F is then swung outward to admit the material to the receivingcase D. Vihen the desired amount of material has been admitted, the plate F is swung into a vertical position, shutting off the feed, the cord 28 is operated to throw the gearwheel 15 into gear with the gear-wheel u, and the rod 7 is operated to throw the half-nuts 51 into gear with the screw 2?, and the said screw and the follower 9' will be forced downward, compressing the material into the sack until the lever 22 is tripped by the collar 26, throwing the gear-wheels 15 u out of gear. The filled sack is then removed in the manner hereinbefore described, and replaced by an empty sack, and the operation is repeated as often as may be desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A sacking-press constructed substantially as herein shown and described, and consisting of the receiving-case, having hinged rear plate, the sack-case, the sack-holding pressingthe material, a screw-driving mechanism, and mechanisms for throwing the driving mechanism into and out of gear, as set forth.
